Wolf Spider Update

by Eric Neubauer

To the outside world it may seem like I’ve been in hibernation but that isn’t so. One current project is making face shots part of my wolf spider observation routine. It’s a lot harder than the dorsal and
ventral views I’ve been doing for a long time. A spider needs to be encouraged to stretch up the side of a container for best results and then stay there for more than a second. It’s especially difficult with spiders small enough to balance on the head of a pin. I’m making progress but it till takes multiple attempts and a lot of prodding.

This is a typical Hogna incognita. His/her body is just over 1 mm wide and just over 3 mm long. It most likely left its mother in late October or early November and has been hanging out ever since. They have grown little over the intervening months and regardless of whether they are in captivity or wild, the only notable different is the ones in captivity are fat and the ones in the wild are skinny. In a month or two they will start to grow rapidly and most will mature in July. Sex can only be determined a little before maturity.

I rarely bother to look when it’s cold, but I did this time and found this one still moderately active at 43 degrees. By the way, Dr. Russell Pfau has started the scientific paper for this new species in earnest. I just reviewed a draft yesterday. We’ll be chasing down a several other loose ends in the same genus later this spring, but that will be another story.
